Slightly modified the ext3 mount (next, will reinstall with resierfs);

mboman@linux:~/Desktop> mount
/dev/sda2 on / type ext3 (rw,noatime,data=journal,noacl)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
debugfs on /sys/kernel/debug type debugfs (rw)
udev on /dev type tmpfs (rw)
devpts on /dev/pts type devpts (rw,mode=0620,gid=5)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
securityfs on /sys/kernel/security type securityfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
gvfs-fuse-daemon on /home/mboman/.gvfs type fuse.gvfs-fuse-daemon
(rw,nosuid,nodev,user=mboman)
